Yiyi is a kind, loyal, caring girl. Might be shy at times, but to closest friends is very open. The title in Chinese means “one by one” meaning “one after another.”
I tell Yiyi all my secrets that I tell no one else.

Yiyi has been my best friend sense we met.

YiYi is a mean, straightforward, brutally honest and more of an Anti hero rather than a villain, she will be cruel and honest, never telling any news softly, The girl that you will be frenemies with, mean to you but found common ground in hating somoeone or something, black is her color. Has sever anger Issues and usually gets in screaming matches, the girl you hate that she is right whenever she gives an opinion (mostly unsolicitated) she hates men, woman, anyone but mostly men, the exceptions are kids and soft animals, she loves kids, treats them like little siblings and adores animals like tiny fluffy cows, bunny's but has a 38 cats.
